【Abstract】Based on the statistical analysis of eight benchmarks simulation, this paper proposes selective replication for some read-only shared data, and in-situ communication for write-read shared data. The former means to improve cache average access speed, while the latter’s purpose is to reduce coherence overhead. It extends a more simple method to solve the ping-pong problem. Statistical analysis of simulation shows these two schemes achieve less access latency and better space utilization compared with conventional cache scheme.
